Europa’s oceans are silent.

Jupiter’s  Europa-moon oceans can be dead. So, new research suggests. That there are no lifeforms under that moon’s icy surface. When we think about Europa’s oceans. The Europa moon's oceans. They are not like oceans on Earth. Those oceans remain liquid because the gravity of that moon is very weak. Jupiter’s gravity causes powerful tidal waves. Under. Icy shell of that interesting moon. This tidal force causes the water whirl around that moon’s core. 

"A new study led by Paul Byrne, an associate professor of Earth, environmental, and planetary sciences, raises doubts about whether Europa’s ocean could support life at its base. By analyzing the moon’s size, the composition of its rocky interior, and the gravitational pull it experiences from Jupiter, the research team found little evidence that Europa has the kind of active geology thought to be essential for life. Their results suggest the moon lacks tectonic movement, hydrothermal vents, and other forms of underwater activity that could supply energy to living systems." (ScitechDaily, Scientists Say Europa’s Ocean May Be Too Quiet for Life)

And this thing makes the magnetic field for that moon. The magnetic field. Denies cosmic radiation and radiation that comes from Jupiter’s plasma ring from destroying water molecules on the Europa moon. Europa is the icy water moon. This means that magma, which is the liquid rock under Earth’s shell, is replaced by water in Europa. 

Magnetic field. Forms when the magnetic mineral dust in the water spins around the core of that moon. So, can there be lifeforms in that moon’s ocean? The thing is that there are no things like fish. The creatures that researchers may hope to find are primitive bacteria-type organisms. If those organisms exist, their metabolism will be very slow. 

There is a possibility that those organisms can synthesize oxygen from water. Using electrolysis, which can form when the noble and base metals are near each other. This electrolysis might not be very effective. But if there are no beasts in that ocean, that can be enough for those organisms to maintain their processes. Those things are only guesses. But the thing is that. This moon can also be dead and cold. But the thing is that Europa itself is interesting. That moon can tell. About conditions. What is on icy planets, and why can those planets that can be giant ice giants exist? 

There may be no geothermal energy in Europa. This means that the core of that moon. It can be. A very small. Thing. Without radioactive material. And the energy that keeps the oceans liquid forms when tidal forces and the cryovolcanos cooperate. The cryovolcano forms low pressure. Under the moon’s icy shell, that weak gravity keeps water molecules separate. The tidal forces. Puts those molecules in motion, in the weak gravity. Because of. In weak gravity, water can be liquid in far lower temperatures than on Earth. If there are lifeforms, those lifeforms can hover in the freezing water rather than be on the bottom of the moon. 

We can determine life as a self-replicating structure. Those structures can react and interact with each other. The fact is. Nobody knows what organisms on other planets or moons look like. Some models suggest that. On very low-temperature moons or planets, DNA can create ice bites. These are DNA-controlled. There is a model. That alien organisms can be water ice. And theoretically. The nanobubbles can form a similar structure to the DNA. Those things cannot be stable on Earth. But. In very low-energy, stable conditions, it is possible that the self-replicating structures can exist.

Io and Europa are the most interesting Galilean moons.

"An artist’s concept shows the internal structure of Jupiter’s moon Io. Data from NASA’s Juno spacecraft suggests that Io does not have a shallow global magma ocean and is consistent with a mostly solid mantle (represented by green hues), with substantial melt (yellows and oranges), overlying a liquid core (red/black). Credit: NASA/Caltech-JPL/SwRI, edited." (ScitechDaily, Juno’s Shocking Discovery: Io’s Interior Isn’t What We Expected)

It is not what astronomers thought. There is no solid magma structure on that moon. The tidal forces form magma pockets inside that moon. And that makes Io interesting. It is known for its volcanic activity. And those findings tell that the planet must not have a common magma layer for volcanism. And that means also old planets can have volcanic activity. At least if they have a massive moon that moves particles inside them.

"Is there potential for life on Europa? This icy moon of Jupiter has a massive ocean hidden beneath its icy crust — one that might have the right ingredients for life. Currently en route, our upcoming Europa Clipper mission will explore this mysterious world, searching for clues about its potential habitability. Watch as a NASA scientist explains more.

The Io is quite a large moon. It's smaller than our moon and gravity on its surface is lower than the moon. The lightweight composition of Io makes it possible for Jupiter's tidal forces to move things inside it. So the tidal forces can also create friction that forms the magma pockets under that moon's surface. The lightweight form of Io means that particles have space to move inside it. 

Same way Europa moon can keep its undersurface ocean liquid. The icy shell protects water that the tidal waves keep always in move. The magnetic particles in that water create a magnetic field that keeps water molecules in one form because it protects Europa from the cosmic rays. The Europa may be a harbor for lifeforms. The moon is very light and it's possible that there are some primitive organisms. The Europa clipper spacecraft can give an answer to that question.

There are two astrobiological models about lifeforms that can survive there. 

In some models, there can be some lifeforms that get their oxygen from electrolysis. Those organisms can have electric organs that can break water molecules by electricity that can be like electric eel's electric cells. 

There is also a model of the silicone-based lifeform. That kind of lifeform can be the silicone cell that is controlled by the DNA. Those organisms could be moon or planet-sized things that can be far from the organisms that we know on Earth. They can be far slower than organisms on Earth. The thing why I mentioned those things as organisms is that they are DNA-controlled structures that can send the silicone bites that carry their DNA even to space. 


Could there have been UFOs in Earth's orbit in the 1950s?

Aligned, Multiple-Transient Events in the First Palomar Sky Survey could be artificial objects. Or. They could also be some light reflection...
